ring gear and then carefully lower the cage assembly
into the ring gear bore. The torsion spring must align and
fit into the notch cut into the ring gear.
10.Install remaining nine (9) rollers into the top row of
the roller cage assembly. Place the rollers in the roller
cage slots and press them out toward the ring gear bore.
11. Install the thrust bearing onto the thrust button in the
cover plate. Make sure that the tang on the side of the
thrust bearing is located toward the outer edge of the
cover plate. Use grease or petroleum jelly on the back
side of the thrust plate to keep the bearing in position
while assembling the cover plate assembly to the gear
case.
IMPORTANT: When installing the cover plate, make
sure that the tangs on the armature plate are proper-
ly aligned into the slots on the roller cage. Improper
assembly can cause damage to the armature plate
and will prevent 4WD from engaging.
12.Place the cover plate onto the gear case assembly.
Make sure to line up the tangs on the armature so they
will insert into the mating slots on the roller cage. Also,
make sure to align the cover plate bolt holes with the
threaded holes in the gear case.
13.Position plug clip to correct location on cover plate
and secure cover plate to gear case with five (5) flange
head screws. Torque screws from 14 to 17 ft−lbs (19 to
27 N−m).
